Referring to FIG. 1, a personal communication service apparatus to which the present invention is applied includes a personal communication terminal (MS) 10 that communicates while moving, and a base station (BTS: Base) that controls the plurality of MSs 10. Transceiver System) 20,

A base station controller (BSC) 30 for controlling the BTS 20, an analog subscriber telephone (A-phone) 70,

TDX-10 Personal Communication Exchange (TDX-10 PCX: TDX-10 Personal Communication Exchange) 400 that handles communication between BSC 30 and analog subscriber phone 70; and TDX-10 PCX 400; A mobile subscriber location information processor (HLR) is connected to the home location register (HLR) 50, and an authentication center (AC) 60 connected to the HLR 50 to manage authentication information.

The TDX-10 PCX (400) is connected to the BSC (30) and performs a personal communication subscriber matching function (ASS_W: Access Switching Subsystem for Wireless) (ASS_W) 400, the internal connection network processing An Interconnection Network Subsystem (INS) 420 to perform, and a Visitor Location Register (VLR) connected between the ASS_W 400 and the INS 420 to perform visitor location registration. 430.

In addition, the ASS_W 410 may include a digital CEPT1 interface (DCI) 411, a time switch processor (TSP) 412, and a No. 7 signal processor (NO7: No. 7 Signaling Message Handling Processor (413), a Personal Communication Access Switching Processor (ASP_W) 414, and an Analog Subscriber Interface Processor (ASIP) 415. The INS 420 is composed of a Number Translation Processor (NTP) 421 and an Interconnection Network Processor (INP) 422.

The software block required for the local code processing of the present invention is as follows.

First, a Personal Communication Subscriber Interface (PCS) block, a PCC Subscriber Call Control (PCC) block, and an Analog Subscriber Call Control (ASC) are loaded into the ASP_W 414. Call Control) and Call Processing Shared Library (CSL) blocks, and the TSP 412 includes a Time Switch And Data Link Control (TSL) block and the NO7 (413). No.7 Signaling Control (S7C) block, Analog Subscriber Interface Control (ASI) block for ASIP 415, and Number Translation (NTR: Number) for NTP 421. TRanslation block, PCS (Pcs Paging Control) block, SNC (Switch Network Control) block at INP 422, Local Location Control (LCC) at VLR 430 Control) block, the HLR 50 has a personal communication application part. A PAP application part control (PAP) block is loaded.

In this case, the signaling system 31 between the TDX-10 PCX 400 and the BSC 30 uses IS-651 that complements No7 (MTP, SCCP), and the TDX-10 PCX 400 and the VLR ( The signal processing 32 between the 430, the HLR 50, and the AC 60 processes a message based on IS-41 (version-C), which is a MAP (Mobile Application Part) standard.

The personal communication service device having the configuration as described above is transmitted to the base station controller 30 through the base station 20 when the mobile terminal 10 makes an outgoing call request. 400, the exchange 400 receives this to generate a calling party's call processor (PCC).

The calling processor (PCC) takes the subscriber's data from the visitor location registration processor 430 to control the calling signal, and the exchange 400 translates the called number to generate an analog fixed subscriber called processor (ASC).

The originating / receiving processor (PCC, ASC) transmits and receives data in the exchange 400, and the originating processor (PCC) transfers the call requested by the calling subscriber to the called party, and the call processed by the called subscriber is received by the calling processor (ASC). ) Controls and delivers it to the calling party. If all call processing is successful, the call service is provided to both subscribers.

Referring to FIGS. 1 and 2, in the personal communication service, a method of processing a local call between a mobile subscriber origination and an analog fixed subscriber call is first performed by the personal communication service when the personal communication service attempts to make an outgoing call. Is transmitted to the base station 20, and the base station 20 passes through the base station controller 30 to the PCC which is an internal block of the ASP_W 414 of the personal communication switch 400.

Upon receiving this, the PCC examines the state of the exchange (202), terminates the call if the exchange cannot perform call processing (203), and generates an outgoing PCC process for call processing if it is normal ( 204).

The originating PCC transmits an authorization information request message requesting information on a personal communication subscriber to the originating VLR 430 (205), receives the subscriber's data as an authorization information notification message (206), and receives the received authorization. The information in the information notification message is examined (207). If the subscriber is not capable of originating, the call is terminated (208). If the subscriber is capable of originating, it is examined whether the subscriber requires authentication (209).

As a result of the investigation (209), if the subscriber is required to authenticate, the terminal authenticates (210) the terminal. If the terminal fails to authenticate, the call is terminated (211).

At this time, only when the authentication is not required or when the authentication is successful, a message (call paging notification) is transmitted to the PPC block of the NTP (21).

When the originating PCC receives the call setup message from the terminal (213), it transmits a call progress message (214), and puts the called number in the call request message received from the terminal on the batch number translation request message, and sends it to NTR of NTP. Require number translation (215).

The NTR is requested to translate the number and transmits the analog fixed subscriber local call notification message to the calling PCC as a result of receiving the translated number.

The originating PCC then receives this and sends a channel establishment request message for wired channel allocation between the exchange and the base station controller to the originating BSC (217), receives a channel establishment notification message (218), and succeeds / fails the channel assignment. It is determined whether or not (219).

As a result of the determination (219), if the channel allocation fails, the call is terminated (220). If the determination is successful, the allocated channel information of the exchange period is stored with the base station controller (221).

At this time, the NTR sends an analog subscriber home call notification to the originating PCC, and simultaneously sends an incoming call request message to the incoming ASP_W with the called party (222).

Having received the incoming occupancy request message, the ASC checks whether the incoming call processing of the subscriber is possible (223). If the incoming service is available, the ASC generates an incoming ASC process (224). After sending the message (225), the call is terminated (226).

The incoming ASC process generated in step 224 carries the information of the called party to the called PCC by placing the information of the called party in the incoming occupancy notification message (227), and the receiving PCC receives the switch connection request for the switch connection between the calling party and the called party. Send a message to the SNC (228).

In addition, the originating PCC receives a switch connection notification message from the SNC (229) and determines whether the switch connection is successful or failed (230), and if the switch connection fails according to the determination result, notifies the call failure message to the called ASC. After the call process ends (231) (232), if the switch connection is successful, the switch connection information notification message carrying the connected switch information is forwarded to the destination ASC (233).

On the other hand, after receiving the switch connection information notification message, the incoming ASC stores the connected switch information (234), transmits the ring to the called subscriber (235), and transmits the ringback tone to the calling party (236), the call notification The message is sent (237).

Then, the originating PCC receives the call notification message and transmits the call message to the originating BSC (238).

The incoming ASC receives the subscriber response message from the A-phone when the called party picks up the receiver (239), cuts the ring sent to the called party and the ringback tone sent to the calling party (240), and sends the incoming response notification message to the calling PCC. After transmitting (241), the call is in a busy state (242).

The originating PCC receives the incoming response notification message and transmits a connection message to the calling terminal (243). After receiving the connection response message from the calling terminal (244), the calling PCC enters a busy state (245).

In addition, the calling PCC transmits a call history count increase request message to the calling terminal during a call (246) when receiving a call history count increasing notification message from the calling terminal (247), and transfers this information to the calling VLR by sending an authentication status message. 248, the originating VLR forwards it to the HLR (249), and the HLR notifies the AC (250) to match the call history count, which is one of the terminal authentication information, between the terminal and the AC.

The present invention as described above has the advantage that the personal communication exchange improves the performance and reliability of the exchange by providing convenience to the subscriber by providing a call service between the mobile subscriber receiving the personal communication service and the existing analog fixed subscriber. ,

In the personal communication service, a private communication service that provides a communication service between two subscribers by accommodating existing analog fixed subscribers and mobile subscribers in a personal communication exchange, and provides a method of handling a local call between a mobile subscriber origination and an analog fixed subscriber call.
